Coverage control is a fundamental problem in sensor networks, which has been explored thoroughly based on a traditional scalar sensing model. However, camera sensors are different from traditional scalar sensors as different cameras from different positions can form distinct views of the target. Hence, Target size and geometric structure of camera nodes can greatly influence the surveillance ability of a camera network. In view of this, a novel observation reliability model of a camera network is proposed, and relationship between surveillance ability and observing reliability for the target is studied. On the basis, a camera network coverage model which considers about obstacles and interesting area of the environment is investigated, and optimized by dynamic planning method. Simulation results show that our method can effectively improve the target capture rate of the network and also we can observe the target from a better view.
